Application filedV February 5,1915, Serial No. 6,237.

relates particularly to an improved dumpV car construction. The invention has among its objects the production of a device of the kind described that is simple, convenient, eliicient, durable and satisfactory. The invention has particularly amongY its objects the production of an improved dumping.

mechanism for controlling the lowering and raising of the dump doors, andV locking the same in position. Other objects and VYadvantages will appear to those skilled in the art from the disclosure herein given. l

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

It may be mentioned that the running gear or trucks, brake mechanism, etc., are not shown in the drawings, inasmuch'as the same is not required :for the purpose of illustrating or describing the present invention, and further since the same maybe of any preferred or standard construction. The main frame of the car body may also be considerably modified from that shown without departing from the invention, although the construction illustrated is preferred, since it is particularly desirable and is .in itself new and novel. In the preferred construction a center beam, preferably of I form, is extended lengthwise the car, the draft rigging being ordinarily secured thereto at each end. Carried by the center beam 1 are the body bolsters 2, the

ibody frame being carried by the body truck bolsters 3. These several parts are secured to the center beam in any desired manner. It is, of course, obvious that two channels arranged back to back would be the full equivalent of the I beam 1 shown. Carried by the bolsters 2 at each side of the car and extending preferably from end to end of the car areY angle beams Y5*(3. The bolsters also carry the side stakes 7; The form of stake shown is formed at its lower end to embrace the beams 2, and is secured thereto in any desired manner. It will be noted by securing the stakes in place, as shown, all brackets, Vgusset plates and the like for securing stakes in place are done away with, and greater clearance obtained. Secured to the stakes are the side walls 8, which are oilset, as most clearly shown in Fig. 4, at 8 and 9, and secured to the sides 6 of the angle bars.` y

There may be any number of doors arranged as desired. In the construction shown theya-:e pivotally supported on axes extending lengthwise the car, the pivotal supportbeingl shown at thecenter of the car. As shown,each door 11 is formed with a hinge 13, which is pivotally secured at 14 to brackets 12 carried by the center beam l. When the doors are raised the same forms the floor of the car, and, as will be noted, the doors when closed are substantially flush with the top of the I beam. Theraising and lowering of the doors is controlled by chains 15, or by cables or the equivalent suitably secured to and extended from the edge ofV the door. The chains 15, or their*v equivalents, may be attached to the doors in any desired manner. As most clearly shown in Figs. 8 and 9, I secure a bar or plate 17 at the free edge of each door, the same preferably being stiEened or braced by the brace members 18. To the part 17 are secured one or more suitable brackets 19, one for each chain. The chain is connected to the brackets 19 by a substantially L-shaped member 2O and pin 21. (See Fig. 7 The L-shaped members 20are each substantially in the form of a hook, the same being provided with an extension 22, the parts 20 and 22 form substantially the letter L having a face 23 formed to engage a supporting and locking member hereafter described. The chains may be secured to 2O by a pin 24 passing through a hole in 20, or equivalent means for the purpose.

`Slidably arranged on the angle 5-6 are members 25 (see Fig. 5) for the several doors, which are secured Vto bars 28. In the preferred construction I control a portion of the doors on each side from one end of the car, and the remaining doors adjacent the other end from the other end. This, however, is a matter of preference, as the doors, or the raising and lowering of the same, may

be controlled, for example, from one end only, 1f so desired. The chains or flexible raising members are secured through the memebrs 25 to a bar 28, as mentioned, which is provided with means for moving the same longitudinally. As most clearly shown in Figs. 1, 3, 8, 9 and 11, the beam 5 is formed with a series of openings or apertures therethrough. Arranged at each opening through the beam 5 is a member 31 (see Fig. 3) which is formed with the lugs 32 having a space 33 between them. (See Fig. 6). These members slidab-ly vsupport the chains 15 between their ends, that is, where they are attached to the hooks 20 and the members 25. (See Figs. 3, 6, 9 and 11). Each of the members 25, when drawn back to the position where the doors are closed, is arranged to form a lock for an adjacent hook 20. (See Figs. 1 and Each of the members 25 is formed with a cam or locking face 27, which engages on the face 23 of the extension 22 of the hook or member when the doors are closed, as shown in Fig. 1. The last hook of the end door, however, may be connected to t-he bar in a little different manner, as most clearly shown in Fig. 2. As shown, bar

. 28 is secured to a member 35, which is formed with a threaded portion 37, which is in Y threaded engagement with an internally Vce threaded member or mandrel 38. The member or mandrel 38 is externally threaded, but in the opposite direction, and arra-ngedto engagev a bracket or drum 39, suitably secured tothe car. As shown, bracket or drum 39 is extended as at 40-(see Fig. 2)

andas at 42 (see Fig. 10) Yand 'secured to the angle 5, 6, and the side wall of the car. It may be mentioned that the angle bar 6 is preferably cutaway as at 41, so as to allow room for the parts. member or mandrel 38' is formed as at 43, substantially similar to a capstan head, so that it may be engaged by an operating bar C, so as to shift the same or rotate it in one direction or the other. The chain connecting the last door with the bar 28 is secured by an eyebolt ,36 to bracket 35. The other chains are secured to members 25 by the eyebolts 26, it being understood that any equivalent construction may be employed.

I have illustrated a. latch or locking member 46 arranged to engage an abutment 45. The member 46 is pivotally secured at 47 to a bracket 48, secured to the car, pins 49 and 50 limiting the movement of the same. While 46 is substantially a locking member, it is intended primarily as an indicator to indicate to the operator and call his attentionto the fact that the doors have been drawn to closed positions'and that they are fully locked.

The operation of the device may be briefly described as follows: Assuming that the doors are in the position shown in Figs. 1,

The threaded 2, 3, and the right hand side of Fig. 4, the Y latch 46 being down, as most clearly shown in Fig. 2: To drop the doors the operator throws catch 46 over, so that it is supported by pin 50, or the equivalent. The capstan `bar or operating rod C shown in Fig. 1 may then be engaged in one of the holes in the capst-an head and the same rotated. Because of the threaded engagement the same will move through the bracket, as illustrated toward the right. The threaded rod 37, in engagement therewith on the interior being oppositely threaded, and prevented from rotating by the bar 28, will also move lengthwise tothe right in relation to member 38, and as shown in Fig. 11. It will be particularly noted that by constructing the rod 37 and member 38 as shown, the same are double acting, that is, as member 38 is rotated it'moves lengthwise, and at the same time, owing to the threaded engagement with rod 37, that is moved lengthwise, not only with movement of member 38 lengthwise, but owing to the threaded engagement, 37 is also advanced relative to member 38. As the parts move the part 28 is, of course,

Vmoved, carrying the' members 26. As they move they tend to release thehooks 20, and theV chains slide over the' brackets or members 31, permitting the doors to drop to open position, vas shown in Fig. 11; To raise the thereany direct transverse strain on the bar 28, as the brackets 25am supported from the angle-side 5 of the bar 5 6. It Vshould be particularly noted that the threaded or screw construction for operating the'bar, in itself forms a very simple andeflicient locking mechanism', and that by means of it the doors may be Asupported at-anyY point intermediate their extreme positions of up or down. The chains being adjustably secured to the brackets 25, adjustments for wear, stretching, or other causes may be easily and promptly made. By this construction the well known type of" winding shaft so generally employed. in dump car-constructions is entirely done away with.

Having thus described my lnvention, it is obvious that various immaterial modifications may be made` in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, constiaiction, arrangement or combination of parts herein shown and described. or uses mentioned.
